Abstract:
A card printer is provided which comprises a printhead, a carrier table reciprocatively movable along a movable path in facing relation to the printhead, a drive mechanism for reciprocating the carrier table, a card transfer mechanism for successively feeding each of cards onto the carrier table, and a positioning assembly for appropriately positioning the card on the carrier table. The positioning assembly comprises a pair of stopper pins which is retractably projectable from the carrier table for stopping engagement with the leading edge of the card, and a cam mechanism for causing the stopper pins to project from the carrier table when the carrier table assumes a standby position for receiving the card.
Abstract:
A video signal output circuit used in a TV set to sample the frequency level of an input video signal so that monitored pictures are automatically optimized in quality. A luminance signal is separated from the input video signal by a Y/C separator. A plurality of band-pass filters whose passing frequencies are f.sub.1, f.sub.2, f.sub.3, . . . , f.sub.n detect the frequency spectrum of the luminance signal through sampling. The detected values are sent to a controller attached to an equalizer. The equalizer is controlled so that monitored pictures based on the output video signal are optimized in quality.
Abstract:
A monitor television apparatus equipped with a plurality of input terminals for AV signals and adapted to serve as an output apparatus selectively for a plurality of AV appliances by switching the input terminals, wherein command signals for the AV appliances connected to the input terminals are registered together with input terminal data corresponding thereto. And when any registered command signal is detected, the input terminal switching operation is controlled automatically to produce an output signal from the AV appliance corresponding to the detected command signal. Meanwhile, even when the detected command signal is not any of the registered ones, the relevant input terminals are automatically selected if the detected signal is included in the group stored previously in the memory means and at least one of such grouped command signals is registered correspondingly to the input terminals, hence achieving remarkable enhancement in the handling facility while realizing high efficiency in the manipulation for registration.
Abstract:
An automatic picture adjustment apparatus in which input video signals are subjected to level conversion for picture quality adjustment within a time period which is shorter than one vertical synchronization period so that the picture quality adjustment of predetermined different portions of the raster may be independently corrected.
Abstract:
A video display system has a circuit for sequentially superimposing N (N.gtoreq.2) information signals upon a video signal for display on the picture screen of a television receiver, at predetermined positions in parallel relation, and a circuit for changing the display positions so as to display information signals sequentially from a corner of the picture screen.
Abstract:
A picture display apparatus has respective modes in which it displays at least three different types of pictures in sequence in response to actuations of a single switch. The picture display apparatus may be incorporated within a conventional television receiver having a programmable timer, and in such case the first type of picture is the normal television picture, the second type of picture is a display of the current day of the week and current time, and the third type of picture is a display of programming information stored in the programmable timer. When the switch is actuated within a predetermined time from the occurrence of a characteristic event in the respective mode, the next type of picture in the sequence is displayed. When the switch is actuated after the predetermined time has elapsed, the first type of picture in the sequence is displayed.
Abstract:
A power supply control apparatus for a television receiver has a manually-actuable power switch for switching the power supply of the television receiver between its ON and OFF states, a digital timer for generating a time code representing the current time, a key input for generating a start-time code and an end-time code respectively representing programmable start and end times, a memory for storing the start-time and end-time codes, first and second coincidence detectors for generating first and second coincidence outputs whenever there is coincidence between the generated time code and the stored start-time and end-time codes, respectively, and a conditioning circuit for conditioning the power switch in response to the first and second coincidence outputs, so that the power switch is enabled and disabled, respectively, following the occurrence of the start and end times when the outputs of the timing circuit and the first memory coincide, a second coincidence detector for detecting the coincidence of the outputs of the timing circuit and the second memory and generating a second coincidence output when the outputs of the timing circuit and the second memory coincide, a first circuit responsive to the first coincidence output and for disabling or enabling the operation of the manual power switch, and a second circuit responsive to the second coincidence output and for enabling or disabling the operation of the manual power switch.
Abstract:
Channel selecting apparatus for use with a signal receiver coupled to a first tuning device and a signal recorder coupled to a second tuning device is operable to tune the first and second tuning devices to preselected channels for receiving broadcast frequencies. In one embodiment, the signal receiver is a television receiver including a video display, and the signal recorder is a video tape recorder (VTR). Selectively operable channel selectors, common to the first and second tuning devices supply channel selector signals to determine the tuning condition of both tuning devices. When the VTR is actuated, a locking circuit locks the second tuning device to the tuning condition determined immediately prior to such actuation regardless of a subsequent difference in the channel selector signals. The locking circuit in the absence of the actuation of the VTR, enables the tuning condition of the second tuning device, as well as that of the first tuning device, to be determined by the channel selector signals. A switching circuit has first and second inputs coupled to the first and second tuning devices, respectively, to receive the channels to which the first and second tuning devices are tuned, and an output coupled to the television receiver. The switching circuit, when the VTR is unactuated, connects the output of the switching circuit to the second input thereof. When the VTR is actuated, the switching circuit connects the output thereof to its first input.
