Description

A kind of novel darkroom film cutter

The utility model is a kind of photographic film cut-off knife, and particularly a kind of Film cutter that is applicable to darkroom work is to belong to the photographic laboratory equipment.

Employed film cutter mostly is the common film cutter of no light source at present domestic medical, the photographic dark room, and is independently of one another with safelight, do not contact directly, exist and move inconvenience, light source is far away during cut-parts, a little less than the light, scale shows unintelligible and causes cut-parts not whole, shortcomings such as film waste.In addition, domestic also have a kind of darkroom of China Patent No. 94224230.0 to show number film cut-off knife automatically, and it comprises chassis, cutting knife, it is characterized in that scale shows the number chi light emitting diode and circuit and contact are housed in inside, guiding ruler slides on guide rail, and power supply and switch are housed on guiding ruler.Its shortcoming is: complex manufacturing technology, and the cost height is difficult for making, and only can uses dc source, and the scope of application is little.

The purpose of this utility model is to overcome above-mentioned defective, and providing a kind of can whole move, the light source safety that becomes clear, and scale clear display, film cut regular and simple in structure, easy to operate novel darkroom film cutter.

Foregoing invention purpose of the present utility model realizes by following technical proposals:

A kind of novel darkroom film cutter, comprise handle of a knife, framework, scale plate, it is characterized in that being built-in with several parts of integrated control switch that link to each other with bulb, attaching plug on miniature string shape bulb and upper surface lamp socket that is covered with filter and the framework that is arranged on the handle of a knife side and forming by being arranged on frame front.

Above-mentioned structure makes film cutter and the circuit of light sources of being made up of bulb, integrated control switch, attaching plug organically combine.When using this device, connect power supply after, handle of a knife lifts when being in the cut-parts state power supply and connects the demonstration digital calibration automatically, handle of a knife is depressed cut-parts and is backed down by handle of a knife the contact of integrated control switch when finishing, and realizes above-mentioned goal of the invention thereby bulb power cuts off automatically.

As a kind of improvement of the present utility model is to be provided with the adjustable resistance that is cascaded with bulb, integrated control switch on lamp socket.Can change brightness and make the light source safety that becomes clear, the scale clear display by regulating adjustable resistance like this.

As another kind of improvement the of the present utility model is that filter is lucite or plastic plate, and its color can change along with the difference of film type, when the green film of usability, can use green lucite or plastics instead.

Be widely used in the cutting of film, printing paper in the darkrooms such as medical, photography.

The utility model by said structure, owing on the basis of former no light source film cutter, increased the break-make of circuit of light sources and the control of the action by handle of a knife light source, the two is combination organically, therefore can wholely move and the bright safety of light source and then can reach simple in structure, convenient and reliable operation, the efficient height, film cuts regular, cut down expenses effects such as benefit raising.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the common film cutter of no light source;

Embodiment 1: as shown in Figure 1, 2, a kind of novel darkroom film cutter, comprise handle of a knife, framework, scale plate, be built-in with integrated control switch more than 4 parts that link to each other with bulb 3, attaching plug 1 on miniature string shape bulb 3 and upper surface lamp socket 7 that is covered with plastics filter 8 and the framework 6 that is arranged on handle of a knife 5 sides and form by being arranged on framework 6 front portions.On lamp socket 7, be equipped with the adjustable resistance 2 of contacting mutually with bulb 3, integrated control switch 4.
