Regarding cartridge tape devices that use single-reel cartridge tapes, the objective is to provide a cartridge tape device that is small and capable of a highly reliable tape bus, and has a built-in wound tape. A cartridge holding part that holds the cartridge; a machine reel that is arranged in parallel with the cartridge holding part and winds the tape of the cartridge; and a tape that guides a leader block attached to the starting end of the tape of the cartridge to the machine reel and attaches it to the machine reel. a thread mechanism; a magnetic head that is provided on the opposite side of the machine reel via the tape movement locus of the tape thread mechanism and reads/writes data to/from the tape;
Rotary guide mechanisms are provided on both sides of the magnetic head to press the recording surface of the tape that has been threaded into contact with the magnetic head.

[Industrial Application Field] The present invention relates to a cartridge tape device using a single-reel cartridge tape.

In recent years, there has been a demand for miniaturization of such cartridge tape devices.

[Prior Art] Next, a conventional example will be explained using the drawings. FIG. 4 is a configuration diagram showing a conventional cartridge tape device, and FIG. 5 is a perspective view of the cartridge i-ridge in FIG. 4.

In the figure, 1 is a cartridge containing a magnetic tape 2, and 3 is a leader block attached to the leading end of the magnetic tape 2. Reference numeral 4 denotes a machine reel for winding up the magnetic tape 2 inside the cartridge 1.

5 is a guide provided on the side opposite to the cartridge 1 of the machine reel 4, as shown in the figure. This is a guide plate with M5a engraved on it. 6 is a shaft of a motor (not shown), and 7 is a first arm that is attached to this shaft 6 via an eccentric sleeve 8 and rotationally driven by the motor. Reference numeral 9 designates a second arm having one end pin-coupled to the rotating end of the first arm 7 and the other end provided with a threader pin 10 that can be engaged with the leader block 3.

Further, a third arm 11 is located in the middle of the first arm 7.
A fourth arm 12 is attached to the intermediate portion of the second arm 9 using pins, and a third arm 11
and the fourth arm 12 are attached with a pin, and the first arm 7, the second arm 9. The third arm 11 and the fourth arm 12 form a four-bar rotation link. A guide roller 13 is provided on the lower surface of the fourth arm 12 and engages with the guide groove 5a.

14 is an air tape guide; 15 is a magnetic heald that is disposed between the two air tape guides 12 and reads/writes data to the magnetic tape 2; and 16 is a tension roller that applies tension to the magnetic tape 2. It is.

Next, the operation of the above configuration will be explained. First, cartridge 1
into the magnetic tape device. When the cartridge 1 is set, the threader bin 1 ( ) provided at the tip of the second arm 9 engages with the threader lock 3 .

Then, the first arm 7 rotates counterclockwise in the t1 direction in the figure. Then, the threader pin 10 moves the trajectory T to tl'l' by the guide roller 13 that engages with the guide groove 5a.
Move while moving and move the leader block 3 to the machine reel 4.
guide to the league block engagement groove 4a. The rider block 3 is connected to the machine reel engaging groove 4 of the machine reel 4.
engage a. Next, when the machine reel 4 rotates by a predetermined amount in the direction shown in the figure, the magnetic tape 2 becomes like a two-point parallel line shown in the figure, a predetermined tension is applied, and the threading of the magnetic tape is completed. .

[Problems to be Solved by the Invention] In conventional cartridge tape devices, there are two types of tape guides: an air guide type like the above-mentioned air tape guide 14, and a fixed roller guide type.

However, the air guide type requires a compressor for the air supply phase, which increases lrTIm force and noise, and there are also problems in that a space is also required for arranging the compressor.

Also, since the air guide type and fixed roller guide type are fixed, the trajectory of the leader block must be drawn outside the air guide or fixed roller in the gap where the tape thread is threaded. The problem is that it becomes large.

The present invention has been made in view of the above problems, and its object is to provide a cartridge tape device that is small and capable of a highly reliable tape bus.

[Means for Solving the Problems] The present invention for solving the above problems includes: a cartridge holding section that holds a cartridge having a built-in tape;
A machine reel that is arranged in parallel with the cartridge holding section and winds the tape of the cartridge; a tape thread mechanism that guides and attaches a leader block attached to the starting end of the tape of the cartridge to the machine reel; and the tape thread. A magnetic head is provided on the opposite side of the machine reel through the tape movement locus of the mechanism and performs read/write operations on the tape, and a magnetic head is provided on both sides of the magnetic head to read and write the tape after threading. A rotation guide mechanism is provided for pressing the recording surface against the magnetic head.

[Function] In the cartridge tape device of the present invention, the inserted cartridge is held in the cartridge holding section. Then, the tape thread mechanism is activated to guide the leader block attached to the starting end of the tape in the cartridge to the machine reel, and mount the leader block.

Next, the rotation guide mechanisms provided on both sides of the magnetic head are activated to press the recording surface of the tape that has been threaded against the magnetic head.

Then, the magnetic head reads/writes data on the tape.

[Example] Next, an example of the present invention will be described using the drawings. 1st

Transfer to 5. Then, the leader block 23 is engaged with the leader block engagement groove of the machine reel 25.

Next, the cam gear drive motor 47 is driven to rotate the cam gear 45 in the direction of arrow 1 in FIG. Then, via the connecting arms 48, 49, the rotating arms 41.
42 are rotated in the directions of arrows ■ and ■ in FIG. 1, respectively, and are in the state shown in FIG. 3.

This rotation of the rotary arm 41.42 causes the rotary roller guide 43.44 to move the recording surface of the tape 21a to the magnetic head 3.
8 to suppress it.

Then, the machine reel 25 is driven, the tape 21a comes into sliding contact with the magnetic head 36, and data is read/written from/to the tape 21a.

Further, when the cartridge 21 is to be ejected, the operation described above is reversed.

According to the above configuration, the rotating roller guides 43 and 44 are movable and are retracted during tape threading, so the thread trajectory can be made small.
The device can be made smaller. Also, cartridge 2
Since the distance between the magnetic head 1 and the machine reel 25 and the magnetic head 36 can be increased, a highly reliable tape running path can be formed, and the influence of uneven tape winding can be reduced.
