Disclosed are a sheet pack and a printer, the sheet pack being inexpensive and capable of being easily set onto the printer and simply exchanged with another one, while users can know information such as the quality, size and number of sheets of printing paper contained in the sheet pack. The sheet pack, containing a predetermined number of sheets, has a frame case formed of thick paper, and may include a sheet supply opening, an abutment opening, a pressure contact opening and a separating pad. A recording member for recording information such as quality, size, number, thickness, color or production date of sheets contained in the sheet pack, may also be provided on the sheet pack. The printer, onto which the sheet pack can be removably set includes an information reading unit for reading the information recorded in the recording member when the sheet pack is set onto the printer. The information read by the information reading unit is displayed by a display unit. The number of sheets remained in the sheet pack resulted from subtracting the number of sheets printed from the original number of sheets may also be recorded in the recording member.

The invention provides a data transfer apparatus which makes it possible to perform communication between an apparatus connected to a serial communication system via a communication line and a terminal device provided with an infrared communication unit. A data transfer device is set such that an upstream data transmitter and a downstream data transmitter are connected to each other via the data transfer device. In this state, in response to a command input via a keyboard or a mouse, data to be printed is transmitted to a printing apparatus via the data transfer apparatus. The data transfer apparatus receives at its light receiving device an infrared signal from a personal computer. An infrared communication controller derives the content of data. A controller checks whether the printing apparatus is a busy state or not. If the printing apparatus is available, then the controller switches the state of the data transfer device into a state in which the downstream data transmitter and the coder/decoder are connected to each other. After that, data transfer apparatus receives the data to be printed from the personal computer via an infrared ray, and the received data is transferred to the printing apparatus via the light receiving device, an infrared communication controller, a format converter, a coder/decoder, the data transfer device, the downstream data transmitter, and the a pair of signal lines of a communication line. According to the received data, the printing apparatus performs a printing operation.

A telephone exchange system accommodates a plurality of central office lines and a plurality of telephones and records a telephonic communication in a recording area shared by the plurality of telephones. When predetermined conditions are satisfied, the recording is played back or transferred. The shared recording area can be utilized effectively by erasing a recording after it has been transferred, and by detecting the presence of a voice during a telephonic communication and starting and stopping the recording operation based upon the results of detection. The time at which a recording has been made can be comprehended in the form of a voice when the recording is played back.

Telephone exchange system

A telephone apparatus includes an extension telephone for receiving data from a card, a timepiece unit, and a control unit for alarming a coincidence between time data included in the data received from the extension telephone and time data of the timepiece unit. The control unit performs a display on the basis of display data included in the data received by the extension telephone.

Telephone apparatus capable of setting card unit therein

A communication apparatus such as a telephone set has a hold circuit for putting a telephone call from a communication partner on hold, a release circuit for releasing the telephone call from the on-hold condition, a circuit for informing the communication partner when the telephone call is released and a detect circuit for detecting when the communication partner whose telephone call is on hold breaks the line, e.g. by hanging up. The communication partner is informed of the release of the on-hold condition in accordance with such release and the detection of line break by the detect circuit.
