In this embodiment, the electromagnetic solenoid 15 and the rotary actuator 14 are combined with the drive unit 11, but the dual type rotary actuator 70 may be provided at one end of the shaft 12 to which the blade 10 is fixed.

FIG. 11 is a front view of the dual type rotary actuator, and FIG. 12 is a side view of the dual type rotary actuator. In the dual type rotary actuator 70, rotary actuators of the same structure that rotate one end of the shaft 12 are arranged in two steps in a similar manner. The first stage is a first rotary actuator 71 that directly rotates the shaft 12, and the second stage is a second rotary actuator 72 that rotates the first rotary actuator 71.

The first rotary actuator 71 is provided at one end of the magnetically shielded housing 73. When energized, the shaft 12 is rotated by a predetermined amount in the direction of arrow C, and when the energization is stopped, the shaft is rotated by a predetermined amount. 1

In the housing 73, a pair of three ferrite cores each having a winding are arranged at a predetermined pitch along the trajectory of the permanent magnet that rotates around the shaft. In the present embodiment, the first and second rotary actuators have three pairs of ferrite cores having windings arranged at a predetermined pitch, but even if three or more ferrite cores are arranged at a predetermined pitch. Good.

Dual type rotary actuator 70
The first rotary actuator 71 and the second rotary actuator 71
Since the rotary actuator 72 is basically the same, the operation of the second rotary actuator 72 will be described.

When the state of the broken line is changed to the state of the one-dot chain line, the windings 78a, 78 are arranged so that the pair of ferrite cores 77a repels the magnetic poles of the opposing permanent magnets 74, respectively.
An electric current is applied to d, and an electric current is applied to the pair of ferrite cores 77b so as to attract the magnetic poles of the opposing permanent magnets 74 to the windings 78b and 78e.

Therefore, the non-magnetic member 75 fitted with the permanent magnet 74 moves in the direction of arrow T. When the member 75 moves to the position of the ferrite core 77b, a current is applied to the windings 78b and 78e so as to repel the magnetic poles of the permanent magnets 74 in the pair of ferrite cores 77b. A current is applied to the windings 78c and 78f so as to attract the magnetic poles of the opposing permanent magnets 74.

The member 75 further moves in the direction of arrow T, and stops when it reaches the position of the ferrite core 77c. After that, the minimum current required for holding is passed through the windings 78c and 78f to hold the state of the alternate long and short dash line. The same applies to the case of shifting from the one-dot chain line state to the broken line state. The operation of the first rotary actuator 71 also follows the operation of the second rotary actuator 72.

By using the dual type rotary actuator, space saving and reduction in the number of parts can be expected.

Further, in place of the dual type rotary actuator, a motor capable of rotating in the normal and reverse directions may be used.

Further, in the present embodiment, the blade is provided at the position where the three transport paths intersect in a T shape corresponding to the medium guiding surface of the blade, but at the position where the four transport paths intersect in a cross shape. A blade may be provided, and the blade may be provided with a medium guiding surface corresponding to 180 ° and a medium guiding surface corresponding to 90 ° so as to be positioned by a pulse motor.

According to the first embodiment, the rotation stop position of the blade is set from two to three, so that the degree of freedom in the medium transport direction is increased, and the transport route can be minimized and the transport path can be simplified. Therefore, it is possible to select an optimal recovery route for the automatic recovery operation, for example, at the time of processing a medium during a jam or an abnormal stop, and it can be expected that the efficiency of medium transportation is improved.

In order to realize the present embodiment by using the blade switching mechanism having two blade rotation stop positions, at least three blades must be used to form a triangular route. The number of parts is greatly reduced, and the space inside the device can be saved.

The blade has a convex first medium guiding surface and a concave second medium guiding surface, and when the medium is conveyed between the first and second conveying paths. Positions the first medium guiding surface between the first and second transport paths by the blade switching means, and transports the medium between the first and third transport paths or between the second and third transport paths. The blade switching means causes the second medium guiding surface to move to the first
The transfer direction switching device according to claim 1, wherein the transfer direction switching device is positioned between the third transfer path and the third transfer path or between the second transfer path and the third transfer path. 3. The shaft for fixing the blade and rotatably supporting the blade,
The transport direction switching device according to claim 1, further comprising: a blade switching mechanism having a forward / reverse rotatable drive unit provided at one end of the shaft, and a control unit controlling the drive unit. 4. The drive unit rotates a rotary actuator provided at one end of a shaft to which the blade is fixed and a rotary actuator between a first position and a second position about the shaft. The transport direction switching device according to claim 3, further comprising a rotating means. 5. The rotating means comprises an electromagnetic solenoid for rotating the rotary actuator in one direction, and a return tension spring for rotating the rotary actuator in the other direction when the electromagnetic solenoid is opened. The transport direction switching device according to claim 4. 6. The transport direction switching device according to claim 3, wherein the drive unit is a dual type rotary actuator provided at one end of a shaft to which the blade is fixed. 7. The blade switching mechanism further includes a movable guide having a guide surface facing the second medium guiding surface of the blade and guiding a medium passing through a gap between the transport paths. The transport direction switching device described. 8. The front and back of the medium is determined by the front and back determination unit,
After storing one of the media determined to be the front or back in the temporary storage unit and the medium determined to be the other in the medium storage unit, the front and back of the medium in the temporary storage unit are determined again and the medium is reversed. It is a medium front and back reversing storage device to be stored in a storage unit, wherein the transport direction switching device is used, and the medium determined to be the other by the front and back determination unit is the first one.
The front and back of the medium of the temporary holding section is determined by the front and back determination section, is guided to the second transport path, the third transport path is connected to the medium storage section, the front and back determination When the other part is determined to be the other, the blade switching means positions the second medium guiding surface of the blade between the first and third conveyance paths, and the front and back of the medium of the temporary storage part is set to the front and back determination part. If it is determined to be one, the blade switching means causes the second medium guiding surface of the blade to move to the second and third sides.
A medium front and back reversing storage device characterized by being positioned between the transport paths of the media.
