A printer of the automatically interchangeable character wheel type includes a platen formed lengthwise of the printer to support one surface of a printing sheet, and a carriage guided so as to be reciprocally movable along the platen. The carriage carries thereon contain a housing for containing a character wheel therein, a first shift device for shifting the character wheel in the containing housing to a printing position, a printing hammer for impacting the characters of the character wheel in the printing position, and a second shift device for shifting an ink ribbon to a first position for printing and a second position for standby by the same motor that drives the first shaft device.

By the driving of drive means for the vertically moving member of a type wheel in one way and resiliently holding means for the type wheel, the type wheel is moved upwardly to a position suitable for printing with the vertically moving member of the type wheel by pivotal movement, whereafter the resilient holding of the type wheel by the resiliently holding means is released by the driving of the drive means in the other way, whereby only the vertically moving member of the type wheel is contained in a type wheel containing housing, and by the driving of the drive means in one way after the termination of printing, the type wheel is resiliently held on the vertically moving member of the type wheel by the resiliently holding means, whereafter by the driving of the drive means in the other way, the type wheel, with the vertically moving member of the type wheel, is contained in the type wheel containing housing.

A printing apparatus system includes a plurality of type units each having a plurality of type elements and each being different from the others. Each type unit may be mounted in the apparatus. A detector detects which of the type units is so mounted and produces a detection signal representative thereof. The printing pressure with which each type element is imprinted on a print medium is determined in accordance with the particular type wheel mounted in the apparatus as indicated by the detection signal. Additionally, the amount of advance of an ink ribbon for imprinting a type element on a type unit is determined in accordance with the particular type unit mounted in the apparatus, again as indicated by the detection signal.

A magnetic card discriminator which is equipped with a card reading part, a registration number memory part, an invalid number memory part, a processing part, and an alarm, and which discriminates whether a card registration number magnetically recorded on a magnetic card is an invalid registration number or not; wherein the card reading part reads the card registration number, the registration number memory part stores the foregoing card registration number having been read, the invalid number memory part has previously stored an invalid registration number of a magnetic card not to be used, the processing part compares the coincidence and non-coincidence of the card registration number having been read out from the registration number memory part with the invalid registration number, and actuates the alarm on the basis of the result of the above comparison such as, for example, the coincidence, and then the alarm makes an alarm signal in the combination of, for example, sound and light.

An ink ribbon cassette mounting mechanism is generally constructed with a guiding device for guiding an ink ribbon cassette, housing an ink ribbon and having an engaging part on the wall surface thereof, from a predetermined direction to a predetermined position. An engaging and holding device is engaged with the engaging part on the ink ribbon cassette to hold the same at the predetermined position, when the ink ribbon cassette is shifted from the predetermined direction to the predetermined position; and releases the engagement with the engaging part, when the ink ribbon cassette is further shifted in the predetermined direction.
摘要:
A printing apparatus comprises a type wheel carrying a plurality of type elements and a platen for mounting and advancing a printing paper. A hammer can strike any one of the type elements against the printing paper and an ink ribbon is positionable between the type elements and the paper to imprint a character on the paper when any one of the type elements is struck. The ink ribbon is advanced by a driving mechanism. First, second, and third selecting systems respectively select one of a plurality of degrees of advancement of the printing paper, one of a plurality of time intervals of actuation of the hammer, and one of a plurality of amounts of advancement of the ink ribbon. First, second, and third counters each count pulses from respectively associated first, second, and third pulse generators to, respectively, first, second, and third set values determined by the selected degree of paper advancement, time interval of hammer actuation, and amount of ribbon advancement. First, second, and third control circuits respectively start paper advance, hammer actuation and ribbon advance upon selection by the corresponding selecting systems and stop such paper advance, hammer actuation and ribbon advance when the corresponding counter counts to its set value. The three control circuits are operated in a coordinated manner by a microprocessor.
