Title: Ink jet recording device equipped with key input mechanism
Inventor: HASEGAWA HIROSHI
IPC: B41J2/01
Filed: 1990-06-01
Abstract: PURPOSE:To prevent print quality deterioration and faulty ink discharge and also prevent careless capping action during operation by capping an ink jet recording head if a key input signal is interrupted for longer than a specified time and setting the head in a routine use state for a specified time during the operation of an ink jet recording device. CONSTITUTION:A timer is started to stand-by for an input through a keyboard and if data is entered by key operation, the timer is again started and a printing operation is activated, after checking to determine that a printing instruction is entered through a keyboard with other data. If no data is entered by key operation, the timer is read and if the lapse of time is not longer than a specified time(e.g. 5 sec.), no action is taken until data is entered by key operation. On the other hand, if the lapse time is longer than five sec., a carriage 11 is moved to a capping position to perform a capping action. If a key-entered signal is suspended for longer than a specified time, the recording head is not exposed to an atmosphere for a long time as the head is capped. Therefore, no print quality deterioration or faulty ink discharge occur. In addition, a routine use state is maintained for a specified time, when an ink jet recording device is operated. Consequently, no careless capping action results from the movement of the carriage 11 during the use of the device.

Abstract: PURPOSE:To search the desired piece of music at high speed and to reproduce it when using a magnetic tape reciprocatively recording the plural pieces of music by deciding it by using a range number that the desired piece of music is recorded in an opposite direction, and immediately switching a magnetic tape transport mechanism. CONSTITUTION:A magnetic tape 1 travels in the direction of forward 52, reproduces a signal by a magnetic head 2 and outputs a music signal from an output terminal 11. In such a state, when the piece of music having a music number 9 is desired, the magnetic head 2 reproduces the range number of the music number 9, frame and time from a track. A reproducing part 12 reads the range number and the time, and a range decision part 13 outputs the command of inverting the traveling direction to a traveling direction switch part 14. The switch part 14 switches a capstan 4, which drives the magnetic tape 1 in the traveling direction 52, to a traveling direction 53. Thus, the head is immediately moved to the position of ending the piece of music having the music number 9. Afterwards, by traveling the magnetic tape 1 to the head position of the music number 9, a close distance can be achieved in a short time.

Abstract: PROBLEM TO BE SOLVED: To prevent an intermediate transfer recording medium, from which a transfer forming image is transferred onto a transfer objective article, from shrinking widthwise to accurately superimpose color images, by pressing and holding the intermediate transfer recording media from both sides when the image is formed. SOLUTION: A thermal head 4 as a selective heating device of a printer presses a thermal transfer sheet 2 and an intermediate transfer recording medium 1 together when they overlap each other and generates heat corresponding to image information, so that at least coloring materials are transferred to a receptive layer of the intermediate transfer recording medium 1 from coloring material layers of the thermal thrasher sheet 2 and an image A is formed. In this case, a pair of nip rollers 6a and 6b as a shrink preventive device is arranged almost perpendicularly to the traveling direction of the medium 1 at each of positions in front of and behind the thermal head 4 to nip the medium 1 from both sides while the medium 1 is carried.  Then, the medium 1 and a transfer objective article B overlap each other at a transfer part and are pressed together onto a platen roll 5a by a second thermal head 4a so that only the receptive layer on which the image A has been formed is transferred onto the transfer objective article B.
