Since the small animal trap according to the present invention is configured as described above, the following effects are achieved.
(1) A sensor that detects that a small animal has entered the cylindrical main body from the entrance into the main body, an open / close lid that is opened and closed by a signal from the sensor, a solenoid that controls opening and closing of the open / close lid, and a battery as a power source And a CMOSIC having a mono-multivibrator function and a control unit composed of a solenoid drive transistor can be attached to and detached from the appropriate part of the main body, so that the control device is not tampered with or broken by the mouse. And installation is good.
(2) Since the control device is integrated in a compact and detachable manner, the maintainability is good.
(3) As an operation of the opening / closing lid, the mouse that has entered the main body can be reliably captured by being closed by the reaction of the sensor provided at a position approximately 10 cm away from the center and at least 10 cm from the entrance. .
(4) By managing the sensor signal by the control circuit program, it is possible to manage the ecology of rats.
(5) Since the sensor is also detachably provided on the bottom plate of the main body, it is possible to check the function of the sensor or replace with various sensors to select a sensor that matches the installation environment.
(6) Since the upper lid is configured to be openable and detachable, cleaning can be easily performed when food is placed or when it is soiled.

An inlet is provided in a part of the longitudinal direction of the cylindrical main body, a sensor for detecting that a small animal has entered the cylindrical main body from the inlet in the main body, an open / close lid that is opened / closed by a signal from the sensor, incorporating a control unit composed of CMOSIC a solenoid driving transistor having a battery and a monostable multivibrator function as a solenoid and a power supply for controlling the opening and closing detachably on appropriate sites of the body is a small animal trap.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a front view, a plan view, a rear view, a right side view, and a left side view of a small animal trap that is a specific embodiment of the present invention. FIG. 3 is a right side view showing a state in which the upper lid of the small animal trap of the present invention is opened, FIG. 3 is a control circuit diagram of the small animal trap of the present invention, and FIG. 4 is a flowchart of one embodiment relating to analysis / management data processing. It is.

The present invention is a small animal trap such as a mouse, which is a trap with improved capture efficiency. As shown in FIG. 1 and FIG. 2, the trap of the present invention comprises a cylindrical rectangular parallelepiped main body 1. The main body 1 adopts various materials such as a metal plate and a synthetic resin plate, and is assembled to the rectangular parallelepiped. It will be. One side plate (back plate) 2 in the longitudinal direction of the main body 1 (shown in FIG. 1C) and the left side plate 4 on the opposite side to the inlet 3 in the short direction (in FIG. 1E). In FIG. 1, a plurality of appropriate openings 5 are formed (for example, can be replaced with punch metal or the like), and the upper cover 6 has appropriate openings 5 as shown in FIGS. A plurality of holes are drilled, and can be freely opened and closed via a hinge or the like. An opening / closing lid 7 for controlling opening / closing of the short-side entrance 3 (shown in FIGS. 1A, 1B, and 1D) is provided, and is opened and closed by a signal from a sensor. A power supply for controlling the opening / closing of the opening / closing lid 7 and a control unit 8 are compactly integrated, and the integrated control device 8 can be freely selected and attached to an appropriate part of the main body 1 from known means. To be assembled.
The front plate 9 on the opposite side to the one side plate 2 in the longitudinal direction of the main body 1 is provided with a locking tool 10 so that the upper lid 6 can be locked, and in particular has no opening. Needless to say, the entire main body 1 may be provided with an opening or may not be provided with an opening. In addition, since the opening 5 can visually recognize the captured small animal, it is better to have the opening 5 in a part.
The upper lid 6 is provided on the upper part so that it can be rotated and opened by a support shaft so as to be passed over the back plate 2 and the front plate 9 so that it can be rotated by its own weight. In order to maintain the open / close lid 7 in the open state, the open state is maintained by the operation of the solenoid by the electromagnetic lock means 11 or the like. That is, it is maintained in a horizontal state so as to be substantially parallel to the upper lid 6 as indicated by a dotted line in FIG. At this time, when the sensor 12 detects that the mouse has entered, the solenoid is driven by the sensor signal, and the electromagnetic lock means 11 is instantaneously brought into the closed state (two-dot chain line state shown in FIG. 1A). 7 is swung to close the inlet 3 to capture the rat.
The sensor 12 is provided at a position approximately 10 cm away from the inlet 3 at a substantially central portion of the bottom plate 13 of the main body 1, and a pressure-sensitive sensor is particularly effective.
However, as the sensor 12, an appropriate sensor can be selected from well-known sensors such as a light-shielding sensor that blocks light by a mouse as well as a pressure-sensitive sensor, and a sensor that senses vibration due to body temperature and movement of a mouse.
The food is prepared in a dish or placed directly in a suitable place on the bottom plate 13 of the main body 1, and behind the sensor 12 on the side opposite to the inlet 3. This feeding and unloading can be easily performed by opening and closing the upper lid 6 and attaching and detaching it.

Next, an embodiment of the control circuit will be described with reference to FIG.
The pressure sensor installed in the substantially central portion of the bottom plate 13 in the main body 1 changes to low resistance when pressure is applied by a high resistance body. When the pressure sensor detects pressure, the resistance value Rs of the pressure sensor is Go down.
When the value of Vin = Rs / (Rs + Ra) × Vdd falls below ½ Vdd, the mono multivibrator (general-purpose CMOSIC) is activated. When the trigger signal Vin is input, a signal having a pulse width determined by the CXR is generated, and even when the generated short pressure-sensitive signal is generated, a pulse having a length necessary for driving the solenoid is output. This signal is used as a mouse intrusion signal.
Tr is a transistor for driving the solenoid, and R1 is a base current control resistor of the transistor.
The capture changeover switch is a changeover switch between feeding mode and capture mode. When the feed / capture mode changeover switch is in the feeding mode, even if the sensor generates a signal, the open / close lid for capture is output without closing. , feed bait-when capture mode switch is set to the capture mode lid is closed when there is a sensor output, so that output capture signal, the sensor 12 when the changeover switch is turned OFF is reacted Since the solenoid does not operate, the capturing open / close lid 7 remains open. That is, the feeding signal and the capture signal are connected to a wireless device connected to the main body, and the information is transmitted to a remote server using the Internet, and the group management of the catcher, the feeding state of the small animal, the capture state Are managed (see FIG. 4). Since this state can be maintained by the changeover switch, it is possible to obtain information on how the mouse is in the trap, so that it is possible to analyze the behavior of the mouse.
The capture switch detects that the capture opening / closing lid 7 is closed and is turned off. That is, when the sensor 12 detects a rat with the capture changeover switch turned on, the open / close lid 7 is closed, and a signal that the open / close lid 7 is closed is output as a capture signal. When the capture signal is ON, both the capture switch and the capture switch, R2 functions as a pull-up resistor. Also, when the capture switch is OFF, R3 functions as a pull-down resistor, and R3 consumes current when in a standby state, and therefore has a sufficiently large resistance. Although a large current flows through the battery when the solenoid is driven, the battery is only driven when the open / close lid 7 is closed, and has little effect on battery consumption.
Battery life Ra during murine stand, since almost flowing current in Rs is consumed by previously Ra, the resistance value of Rs in the high-resistance, can be used for a long time with batteries.
By adopting this control circuit, it can be confirmed that the mouse is reliably captured when the capturing open / close lid 7 is closed and the intrusion signal is generated.

  It can be applied not only to rats but also to capturing various small animals.
