A method for producing an information card by printing an electroconductive pattern and a first electrode surface of a battery on a first cover sheet, applying a battery activator onto the first electrode surface, resting an electrolyte-impregnated separator onto the first electrode surface, fixing an IC chip to the electroconductive pattern in a predetermined position, printing a second electrode surface of the battery on a second cover sheet, applying a battery activator onto the second electrode surface, and lapping and sticking the first and second cover sheets together and cutting them into a predetermined size.

Markings on a tape cassette label and on its tape leader cooperate with an inspection system which senses the markings to automatically compare the actual characteristics of the tape marked on the tape leader such as, for example, length and type of magnetic powder, with the characteristics described on the cassette label. In the event that the tape type and label description disagree, an alarm or removing mechanism may be automatically actuated to remove the mislabelled cassette.

A system for selectively supplying information including video information to operators, such as students, at plural stations, the information requiring responses, or answers, and the correctness of each operator's answer being displayed. A television monitor is provided at each station to display video picture information. In reply to a question, which may be displayed or audibly reproduced, a responding device is selectively operated by the operator. The video picture information displayed at each television monitor is stored in a main storage device in the form of video picture signals representing predetermined still video information. Selected ones of the video picture signals are supplied from the main storage device as a function of each response, or answer, by the operators. A buffer store having a plurality of video picture signals storage channels corresponding to the number of stations is coupled to the main storage device to receive the selected video picture signals and to transmit these received signals to particular ones of the stations. A control unit is coupled to the main storage device and to the buffer store for controlling the transmission of selected video picture signals from the main storage device to a particular video picture signal storage channel and for controlling the transmission of video picture signals from the storage channels in the buffer store to selected ones of the stations. In one embodiment, a video display of the correctness of the operator's answer is provided. It is one feature of this system to transmit new video information to each monitor in accordance with the pace, or progress, of each operator.
