Abstract

PURPOSE:To suppress the occurrence of a vibration at the time of unloading by providing a means for releasing a cartridge holding means from its locking state in a 1st moving range of a slide plate. CONSTITUTION:Since, first of all, a guide roller 149 is separated from an engagement surface 1292 of a cam part 129 by moving the slide plate 99, ejecting force is given by an ejecting arm 145 by abutting of a guide roller 150 against a front surface 1531 of a cartridge 153. However, the cartridge 153 is still obstructed on its slant surface 1533 by guide rollers 85 and 86, so that it is held in a cartridge holder 65. When the slide plate 99 is further moved, a releasing arm 124 is engaged with a pin 69, and hence the pin 69 is released from its locking state with an engagement part 98 of an arm 80. When the locking state is released, arms 80 and 81 are turned by energizing force of springs 90 and 91, and the cartridge 153 is ejected from the holder 65 by the arm 145.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cartridge holder/loading device equipped with a cartridge 1/ridge holding means for holding a cartridge fully mounted in a cartridge holder direction. , Rikiichi 1 Ridge Holder 0-
After the cartridge has been brought from the loading position to the unloading position, the cartridge is placed in a cartridge boulder O-ding device which is configured to reduce the force and the 0 state of the cartridge holding means by M.

[Prior Art] Conventionally, a lead-back socket 154 shown in FIG. 39, 8, B
Cartridge 153 with CL: which can be freely attached and detached to leader board 0180 is published in Special Publication No. 61-61470 (U
SP No. 4,383,660), Jikoreki 63-536
No. 33 (LJSP No. 4,426,047), Special Imperial Decree No. 63-53632 (LJSP No. 4.452,406)
I have a complete proposal. To briefly explain this cartridge, a feed reel 155 is housed in the center of the force ridge 153, and a lead tab holder 154 attached to the tip of the tape T completely wrapped around the feed reel ridge 153 is attached to the cartridge 153. The insertion/removal port 180 formed in the corner of the front face l53, one side face 1534
It can be attached and detached at will. Moreover, this car 1., ridge], 53 has a front surface 153. (ε-opposed helical surface 153, and inclined surface 15 formed to be inclined downward of the rear surface 153)
3. The discharge surface consisting of B is designated as B. Further, the lower surface 153 of the cartridge 1.53 has a hole for engaging the positioning pin of the tape drive device], 8]. ,181,
is formed.

This cartridge 153 is based on the American National Standard (ANS I) X3BS/87-072.
The width W is 4174 inches, the length is 4778 inches, the height H is 15/16 inches, and the diameter D of the supply reel 155 housed inside is 33/16 inches.
It is specified as 4 inches.

The applicant of the present application developed a cartridge boulder/loading cap suitable for this cartridge 153 in 1983.
-1, No. 91445, and No. 1914/16.

This cartridge holder/loading device allows a cartridge to be loaded and moves between a loading position and a loading position.・A spring that biases the ridge holder in the direction from the zeroing position to the unloading position, car 1.・A spring force that biases the cartridge to eject the cartridge from the ridge holder.
- A locking means for locking the ridge holder in the zeroing position against the biasing force of the spring, and a single reel that is located within the cartridge ridge holder at the unloading position a and that is completely accommodated in the cartridge. It is completed from the pin t that engages with the release hole of the tape slack prevention device fence formed in the center of the bottom surface. The cartridge can be loaded into the cartridge holder B, and the release hole of the tape loosening prevention mechanism can be engaged with a desired bottle in the cartridge holder, so that the cartridge can be held in the cartridge holder C against the biasing force of the eject arm. Then, the cartridge can be brought to the loading position a by manual operation while the biasing force of the adjustment arm is applied. On the other hand, when the locking means is completely released by the plunger,
The cartridge holder is brought from the loading position to the unloading position by the spring, and at this time, due to its inertia, the cartridge is moved in the unloading direction to a position where the release hole of the tape slack prevention mechanism and the bottle are in a disengaged state a. The cartridge is displaced and ejected from the cartridge holder by the eject arm. [Problems to be Solved by the Invention] According to this cartridge holder/loading device, the cartridge is displaced in the unloading direction within the cartridge holder due to inertia during aflowing, and the held state is released. Therefore, the cartridge holder must be brought to the unloading position at a relatively fast speed by a spring or the like. The vibrations generated at this time may adversely affect the tape drive device equipped with this cartridge holder/loading device, and especially when this tape drive device is installed in a computer equipped with a hard disk drive device. It is considered a problem. On the other hand, in a cartridge holder/loading device that moves between an unloading position and a loading position by moving a slide plate, the cartridge holder is brought to the reel opening position at a relatively slow speed.

Therefore, it is difficult to apply the conventional method to a cartridge holder/loading device using a slide plate because the cartridge does not release its holding state because almost no inertia is generated during unloading. The present invention provides a cartridge holder/loading device that eliminates the n-point problem. [Means for solving the gap U point] The cartridge holder/loading device of the present invention moves a cartridge holder into which a cartridge can be attached in a second direction opposite to the first direction and the direction of the first step. The cartridge holder is held in the unloading position in a first range of movement moving in a second direction, followed by li! moving in a first direction.
In the moving range of step 2, unscrew the cartridge holder.
- bringing the cartridge holder from the loading position to the loading position, and in a second movement range moving in the first direction, bringing the cartridge holder from the O-ding position to the afloating position, and subsequently moving the cartridge holder in the first direction; In the first movement range in which the cartridge holder is moved to the unloading position, a loading means including a slide plate that keeps the cartridge holder in the unloading position is attached to the cartridge holder, and when the cartridge is installed in the cartridge holder, the lock 4 state is established and the cartridge is unloaded. a cartridge holding means held in the cartridge holder; and a slide plate attached to the slide plate and moved in the second direction.
1 of the slide plate 111 that engages with the cartridge holding means but moves in the first direction without releasing the locked state of the cartridge holding means in the movement range of l.
In the first movement range, the cartridge holding means is engaged with the cartridge holding means to release the locked state of the cartridge holding means. [Function] When a cartridge is installed in the cartridge holder at the unloading position, the cartridge is held in the cartridge holder by the cartridge holding means. In the first movement range of the slide plate that moves in the first direction, the cartridge holder is maintained at the 7-in loading position, and the release means for releasing the locked state of the cartridge holding means attached to the slide plate is attached to the cartridge holding means. engages but does not release the locked condition of the force-trip retaining means. Then, in the subsequent second movement range of the slide plate, the cartridge holder is brought from the unloading position to the loading position. On the other hand, in the second movement range of the slide plate moving in the second direction, the cartridge holder is brought from the loading position to the unloading position. Then, in the subsequent first movement range of the slide plate, the cartridge holder is kept at the unloading position, and the release means for removing the dripping state of the cartridge holding means attached to the slide plate is operated by the car 1. - Engages with the ridge holding means and releases the four main locks.
