Electronic equipment comprises a store for storing messages, apparatus for processing time information and generating an output at the beginning of each predetermined time period. The messages and time information may be displayed and one of the messages can be selected at random at the start of each time period and displayed with time information in response to the output of the time information processing means, the same message being prevented from being displayed more than once in a time period that is longer than the first mentioned time period.

A device for controlling the power supplied to windings of a stepping motor includes a pulse generator for splitting one step drive period of the motor into a plurality of sections, the number of sections and increasing or decreasing depending upon the drive frequency. The pulse generator, also sets the duty cycle of a pulse applied to the motor. The device also includes a stepping motor drive circuit for exciting each phase of the motor with a current determined by the duty cycle of pulse, and a duty changing device for changing the duty cycle for each of plural sections in one excitation phase of the stepping motor, wherein a current wave input into the motor can be maintained as a sinusoidal wave from low-speed rotation to high-speed rotation of the motor by changing the number of sections in excitation depending upon serial drive operations, thereby achieving motor control with less rotation inconsistencies and less noise.

An ink jet recovery device comprises an elastic cap that is movable between a retracted position, in which it is spaced from a recording head, and a contact position, in which it is pressed against and seals the recording head. The recovery device also includes a rotatable drive gear having a cam surface, with a retracting cam and a compression cam, for moving the cap. When the drive gear is in a first angular position the retracting cam moves the cap to its retracted position, and when the drive gear is in a second angular position the compression cam presses the cap against the recording head. The drive gear has a third angular position for disengaging the pin from the cam surface so that a spring can press the cap into the contact position. In operation, the compression cam further presses the cap toward the recording in order to force air into the recording head to aid recovery.

A cursor movement control key switch for controlling movement of a cursor on a display screen of a CRT or the like requires only one key. Operation of a single key allows both control of the direction of the cursor, and control of brightness of the display, volume level of sounds at a speaker, a display size of the cursor or the like. A CPU periodically detects the states of signals at terminals corresponding to contacts disposed in the key switch so as to produce signals to perform the above control operations. The key switchy provides improved operability.

This invention relates to a system which improves an operation speed and accuracy of judgement when the posture of an object component parts is judged by an image processor. This system determines a combination of parameters used for the posture judgement at the time of the preparation of standard data, classifies the types in accordance with the parameter combinations and makes processing for a parameter combination designated for each type at the time of recognition, thereby judging the posture of the object component parts at a high speed and with a high level of accuracy.

An object of the present invention is to provide a print medium identifying device that can accurately detect various print media. Thus, according to the present invention, a light emitting section (LED) irradiates a surface of a print medium P with ultraviolet light and different light of a longer wave. A light receiving section (regular-reflection photo sensor and diffusive-reflection photo sensor) receives the light reflected by the surface of the print medium P to output a signal corresponding to the quantity of light received. Identifying section (signal processing section) identifies the type of the print medium on the basis of a signal output by the light receiving section when the print medium is irradiated with the ultraviolet light and a signal output by the light receiving section when the print medium is irradiated with the different light.

A storage container for housing and storing an ink jet cartridge which has a recording head to discharge ink, and an ink tank to contain ink to be supplied to the recording head and which is structured to be exchangeable with respect to a recording apparatus comprises a capping member to be in contact with the ink discharge port surface of the recording head to cover the surface thereof and absorbing members conductively connected to the capping member to absorb ink which leaks from the recording head. With the capping member and absorbing member, an airtightness higher than that of the discharge ports is obtained in order to suppress the ink evaporation from the discharge ports of the recording head while the cartridge which is still in use is kept in the storage container.

An ink jet recording apparatus for recording by infiltrated ink into a recording sheet or by fixing ink through evaporation of an ink solvent includes an ink jet recording head for ejecting ink onto the recording sheet at a recording area of the apparatus where the recording head is opposed to the recording sheet. The apparatus also includes a heating member extending both upstream and downstream with respect to the recording area and a conveying direction of the recording sheet. The heating member contacts the recording sheet to assist in the fixation of the ink. The apparatus further includes a press plate, disposed upstream of the recording area with respect to a conveying route of the recording sheet, for pressing the recording sheet against the heating member. The press plate has a portion opposed to the heating member and a plurality of slits spaced apart from each in a direction perpendicular to the conveying direction of the recording sheet. The apparatus also includes a conveying member for discharging the recording sheet from the printer. The conveying member is provided downstream of the recording area with respect to the conveying direction. The heating member extends to a position opposed to the conveying member.
